The value of type double? property in class is confusing about netcoredbg HOT 4 OPEN

https://github.com/dotnet/runtime/blob/135fec006e727a31763271984cd712f1659ccbd3/src/libraries/System.Private.CoreLib/src/System/Nullable.cs#L21-L75
Looks like fields was not initialized by constructor before real code execution during evaluation (properties getters calls).
Is this case provide same issues:

internal class Variables { public double? DoubleValue{get;set;} }

static void Main(string[] args) { var variables = new variables();  
;//breakpoint here, check values } 

?

Yes, that case provide same issues.

Hmm... strange, because HasValue code is
https://github.com/dotnet/runtime/blob/135fec006e727a31763271984cd712f1659ccbd3/src/libraries/System.Private.CoreLib/src/System/Nullable.cs#L33-L37

        public readonly bool HasValue
        {
            [NonVersionable]
            get => hasValue;
        }

and hasValue=false, HasValue = true could happens only in case
https://github.com/dotnet/runtime/blob/135fec006e727a31763271984cd712f1659ccbd3/src/libraries/System.Private.CoreLib/src/System/Nullable.cs#L27-L31

        public Nullable(T value)
        {
            this.value = value;
            hasValue = true;
        }

not called first (before getter call) and hasValue have default (false) value.

Could you please provide full code (with DoubleValue property initialization) you are using for testing?

If they are indeed correct, I want to directly display the null value ​​and show the actual value，what should I do?

We don't support System.Nullable<> for now, so you could see only internal members (instead of "real" value).

Hmm... looks like works different for public double? DoubleValue; and public double? DoubleValue{get;set;}. Will add this in investigation list.
